-** Each SQL table is represented in memory by an instance of the
-** following structure.
-**
-** Table.zName is the name of the table.  The case of the original
-** CREATE TABLE statement is stored, but case is not significant for
-** comparisons.
-**
-** Table.nCol is the number of columns in this table.  Table.aCol is a
-** pointer to an array of Column structures, one for each column.
-**
-** If the table has an INTEGER PRIMARY KEY, then Table.iPKey is the index of
-** the column that is that key.   Otherwise Table.iPKey is negative.  Note
-** that the datatype of the PRIMARY KEY must be INTEGER for this field to
-** be set.  An INTEGER PRIMARY KEY is used as the rowid for each row of
-** the table.  If a table has no INTEGER PRIMARY KEY, then a random rowid
-** is generated for each row of the table.  Table.hasPrimKey is true if
-** the table has any PRIMARY KEY, INTEGER or otherwise.
-**
-** Table.tnum is the page number for the root BTree page of the table in the
-** database file.  If Table.iDb is the index of the database table backend
-** in sqlite.aDb[].  0 is for the main database and 1 is for the file that
-** holds temporary tables and indices.  If Table.isTransient
-** is true, then the table is stored in a file that is automatically deleted
-** when the VDBE cursor to the table is closed.  In this case Table.tnum 
-** refers VDBE cursor number that holds the table open, not to the root
-** page number.  Transient tables are used to hold the results of a
-** sub-query that appears instead of a real table name in the FROM clause 
-** of a SELECT statement.

-** SQLite supports many different ways to resolve a contraint

-** but the transaction is not rolled back.  FAIL processing means that
-** the operation in progress stops and returns an error code.  But prior
-** changes due to the same operation are not backed out and no rollback
-** occurs.  IGNORE means that the particular row that caused the constraint
-** error is not inserted or updated.  Processing continues and no error
-** is returned.  REPLACE means that preexisting database rows that caused
-** a UNIQUE constraint violation are removed so that the new insert or
-** update can proceed.  Processing continues and no error is reported.
-**
-** RESTRICT, SETNULL, and CASCADE actions apply only to foreign keys.
-** RESTRICT is the same as ABORT for IMMEDIATE foreign keys and the
-** same as ROLLBACK for DEFERRED keys.  SETNULL means that the foreign
-** key is set to NULL.  CASCADE means that a DELETE or UPDATE of the
